Benefits of technology

"The present invention is a system for removing unwanted contaminants from run-off water. It uses a combination of settling, agglomeration, and filtering to remove suspended particulate matter. The system employs a plurality of elongated, closed filter bags constructed from a filtration fabric. The bags act as a dam to pool water for settling and as an agglomeration polymer to hold colloidal particles in suspension. The system also uses a skirt that is impregnated with a polymer to induce further agglomeration and prevent breakthrough of higher velocity water streams. The skirt restrains water flow and acts as a backup to prevent erosion control. The system effectively removes colloidal particles and achieves water clarity. The invention provides a unique combination of settling, agglomeration, and filtering to remove unwanted contaminants from run-off water."

Problems solved by technology

In the development of subdivisions and shopping centers, in urban expansion, and in road and highway construction, huge quantities of earth often must be either removed or disturbed leaving large areas of exposed land without any cover or means to prevent erosion.
Most of the prior products do not provide compliance with the new act.

Embodiment Construction

[0041]Referring now in more detail to the drawings, the invention will be described in more detail.

[0042]FIG. 1 illustrates a simple job site of a residential home 10 having a downward slopping lot 12 which is provided with an erosion control and water clarification system, designated generally as A, employing an arrangement of filter bags, designated generally as B. The front row of filter bags B includes water clarification skirts C. The same may also be provided on the side row of filter bags, if desired. As can best be seen in FIG. 2A, filter bag B includes a filter fabric 14 formed into an elongated, tubular filter bag B. For example the bag tube may be formed with a longitudinal seal, or two side seams and the seams may be sewn, thermal or adhesively bonded, and the like. In some instance, a seamless woven tube may be used. One end of the bag, 14a is closed and the other end of the bag 14b may be opened for filling and then closed by any suitable means. The bag may be provided...

Abstract

An erosion control system and method wherein a fabric filter bag is embedded with and / or filled with a flocculating polymer and is positioned on a sloping soil surface to dam and pond water flowing thereacross for settling of the particles in the water, and as the ponding water seeps into the bag the colloidal particles will be filtered or agglomerated for settling. The water then passes through and out of the bag and is further subjected to agglomeration and filtering by a skirt of filter material also impregnated with flocculating polymer, said skirt being anchored to the bag or stacked to maintain the position adjacent and downslope from the bag.

Description

CROSS REFERENCE TO RELATED APPLICATION / CLAIM OF PRIORITY[0001]This application claims priority under 35 USC §120 from U.S. provisional application Ser. No. 60 / 831,835 filed Jul. 19, 2006 entitled “Polymer Filtration System and Method for Erosion Control and Water Clarification”.FIELD OF THE INVENTION[0002]This invention relates to a system and method for capturing particles in runoff water from sites undergoing grading, landscaping, mining maintenance, logging, road building, land fills, utility and building construction, and other types of soil and environmental disturbances and for controlling erosion at such sites. The erosion control method of the invention is also useful for controlling flash flooding in flood prone areas, in areas subject to hazardous fires, in areas requiring industrial waste management and in containing environmental spills and nuclear wastes. The invention particularly relates to a system and method employing filters, settling, and polymeric removal of soli...
